Added 2006 copyright. At SuSE's suggestion, enabled all error messages without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, respectively. This preserves all error and warning messages in the non-debug version of the ACPICA code (this has been referred to as the "debug lite" option.) Over 200 cases were converted to create a total of over 380 error/warning messages across the ACPICA code. This increases the code and data size of the default non-debug version by about 13K. Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages. The size of the debug version remains about the same.
